#3. Warren Buffett – Omaha, Nebraska

Although the shrewdest investor on earth holds multiple real estate investments, Mr. Buffett is known for living humbly. His home sits on a corner in Omaha, Nebraska, which he bought in 1958 for $31,500. Mr. Buffett has lived there ever since. The house, originally built in 1921, underwent several expansions to make it a cozy and comfortable 6,500-square-foot home for the man who has a net worth of over $65.5 billion.
